$2+19*[\frac{2,652:1,3-1\frac{17}{30}+\frac{3}{50}}{24:6,4-(12:3\frac{3}{5}+\frac{2}{5})*0,5-1,25} ]-3+2*2$=

$\frac{2652}{1000}:\frac{13}{10} -\frac{47}{30}+\frac{3}{50}}$ = $\frac{2652}{1000}*\frac{10}{13} -\frac{47}{30}+\frac{3}{50}}=\frac{3)204}{100}-\frac{10)47}{30}+\frac{6)3}{50}$= $\frac{612-470+18}{300} =\frac{160(20}{100} =\frac{8}{5}$

$24:\frac{64}{10} -(12:\frac{18}{5}+\frac{2}{5})*\frac{1}{2} -\frac{125}{100}$ = $24*\frac{10}{64} -(12*\frac{5}{18}+\frac{2}{5})*\frac{1}{2} -\frac{5}{4}$ =

=$3*\frac{10}{8} -(2*\frac{5}{3}+\frac{2}{5})*\frac{1}{2} -\frac{5}{4}$ = $\frac{15}{4} -(\frac{5)10}{3}+\frac{3)2}{5})*\frac{1}{2} -\frac{5}{4}$ = $\frac{15}{4} -\frac{56}{15}*\frac{1}{2} -\frac{5}{4}$ = $\frac{15)10}{4} -\frac{4)28}{15}$ = $\frac{150-112}{30}$=$\frac{38}{30}$=$\frac{19}{15}$

2+19*$\frac{5}{8}$:$\frac{19}{15}$-3+4=3+19*$\frac{5}{8}$*$\frac{15}{19}$=3+$\frac{75}{8}$=3+9,375=12,375
